Abstract
We examine the quantum phase transition at zero temperature between paramagnetic and spin-glass-ordered phases as the strength of a uniform transverse field, Γ, is varied. At the critical point, , the spin autocorrelation function decays with time, t, as . As the transition is approached from the paramagnetic phase the nonlinear susceptibility diverges as {‖ln(Γ-)‖/(Γ-).
